Title: Liquid crystal electrooptic element
Inventor: OKUMURA OSAMU
IPC: G02F1/1341
Filed: 1987-04-06
Abstract: PURPOSE:To prevent disturbance in orientation of liquid crystal molecules at the time of sealing a liquid crystal and to improve the contrast ratio of a liquid crystal electrooptic element by providing a guide groove for the liquid crystal near the liquid crystal injection hole of at least one of substrates. CONSTITUTION:The liquid crystal guide groove 5 is provided by etching on the lower substrate 1 so as to be positioned perpendicularly in the rubbing direction of the substrate and right under the liquid crystal injection hole 4 of the upper substrate 2. The upper substrate and the lower substrate are adhered to each other via a sealing material 3. The inside and outside of this empty cell are maintained in a vacuum state and the liquid crystal is sealed therein. The liquid crystal, therefore, infiltrates preferentially into the part of the liquid crystal guide groove where the cell thickness is large at the time of the injection thereof; thereafter, the liquid crystal begins to infiltrate into the thin part of the cell. Since, the liquid crystal infiltrates into the cell along the rubbing direction of the substrates in this case, the orientation of the liquid crystal molecules is hardly disturbed. The contrast ratio of the liquid crystal electrooptic element is thereby improved.

Title: Manufacture of coil winding
Inventor: ISAGAWA MITSUO
IPC: H01F41/06
Filed: 1984-04-25
Abstract: PURPOSE:To minimize contact failure of contacts by coating the surface of lead wire having an insulation film with paraffin, forming a coil with such lead wire and thereafter eliminating volatile materials under a particular temperature and a reduced pressure. CONSTITUTION:The surface of lead wire having an insulated film is coated with paraffin, a coil is formed with such lead wire, thereafter volatile material is eliminated under a temperature of 85 deg.C or higher and a reduced pressure of 1X10<-2>Torr of less. Any kind of paraffin can be used because it is used for obtaining good sliding at the time of forming a coil. Relation between the paraffin and contact resistance of contacts depends on saturated vapor pressure of paraffin and any influence is not applied on the contacts under the vapor concentration of 1X10<-2>Torr or less. Processing time of reduced pressure and heating conditions can be determined freely. Since the surface of coil winding film is usually only coated with liquid paraffin, such film is momentarily volatiled only when it is exposed under the ambient of 1X10<-2>Torr.

Title: Digital signal delay circuit
Inventor: MIKI YASUHIKO
IPC: H03K5/133
Filed: 1984-04-27
Abstract: PURPOSE:To realize plural delay operations whose delay times are independently settable by using one group of delay elements in common to plural delay parts. CONSTITUTION:A clock signal A is supplied to a terminal 10 and delayed by delay elements 12-18 to obtain delay outputs B-E. When a digital input signal F is supplied to an input terminal 36 and an MPX20 selects the signal A, the digital output signal G of an FF28 appears at its output terminal 44. When the MPX20 selects the clock signal B, a signal H appears at the terminal 44 and is delayed the delay time of the delay element 12 behind the signal G. When the MPX20 selects the signals C, D, and E, output signals I, J, and K are obtained similarly. The delay time corresponding to the signal G is the sum of delay times of corresponding delay elements. Further, delay parts 22-30, 24-32, and 26-34 also operate as mentioned above. Thus, delay times are controlled independently at respective delay times to control phase differences of output signals at terminals 44-50 freely.
